Plain
(1.) Heb. 'abel (Judg. 11:33), a "grassy plain" or "meadow."
Instead of "plains of the vineyards," as in the Authorized
Version, the Revised Version has "Abel-cheramim" (q.v.), comp.
Judg. 11:22; 2 Chr. 16:4.
(2.) Heb. 'elon (Gen. 12:6; 13:18; 14:13; 18:1; Deut. 11:30;
Judg. 9:6), more correctly "oak," as in the Revised Version;
margin, "terebinth."
(3.) Heb. bik'ah (Gen. 11:2; Neh. 6:2; Ezek. 3:23; Dan. 3:1),
properly a valley, as rendered in Isa. 40:4, a broad plain
between mountains. In Amos 1:5 the margin of Authorized Version
has "Bikathaven."
(4.) Heb. kikar, "the circle," used only of the Ghor, or the
low ground along the Jordan (Gen. 13:10-12; 19:17, 25, 28, 29;
Deut. 34:3; 2 Sam. 18:23; 1 Kings 7:46; 2 Chr. 4:17; Neh. 3:22;
12:28), the floor of the valley through which it flows. This
name is applied to the Jordan valley as far north as Succoth.
(5.) Heb. mishor, "level ground," smooth, grassy table-land
(Deut. 3:10; 4:43; Josh. 13:9, 16, 17, 21; 20:8; Jer. 48:21), an
expanse of rolling downs without rock or stone. In these
passages, with the article prefixed, it denotes the plain in the
tribe of Reuben. In 2 Chr. 26:10 the plain of Judah is meant.
Jerusalem is called "the rock of the plain" in Jer. 21:13,
because the hills on which it is built rise high above the
plain.
(6.) Heb. 'arabah, the valley from the Sea of Galilee
southward to the Dead Sea (the "sea of the plain," 2 Kings
14:25; Deut. 1:1; 2:8), a distance of about 70 miles. It is
called by the modern Arabs the Ghor. This Hebrew name is found
in Authorized Version (Josh. 18:18), and is uniformly used in
the Revised Version. Down through the centre of this plain is a
ravine, from 200 to 300 yards wide, and from 50 to 100 feet
deep, through which the Jordan flows in a winding course. This
ravine is called the "lower plain."
The name Arabah is also applied to the whole Jordan valley
from Mount Hermon to the eastern branch of the Red Sea, a
distance of about 200 miles, as well as to that portion of the
valley which stretches from the Sea of Galilee to the same
branch of the Red Sea, i.e., to the Gulf of Akabah about 100
miles in all.
(7.) Heb. shephelah, "low ground," "low hill-land," rendered
"vale" or "valley" in Authorized Version (Josh. 9:1; 10:40;
11:2; 12:8; Judg. 1:9; 1 Kings 10:27). In Authorized Version (1
Chr. 27:28; 2 Chr. 26:10) it is also rendered "low country." In
Jer. 17:26, Obad. 1:19, Zech. 7:7, "plain." The Revised Version
renders it uniformly "low land." When it is preceded by the
article, as in Deut. 1:7, Josh. 11:16; 15:33, Jer. 32:44; 33:13,
Zech. 7:7, "the shephelah," it denotes the plain along the
Mediterranean from Joppa to Gaza, "the plain of the
Philistines." (See VALLEY.)
